I've had nothing but headaches with the facedetect library. I had much  
better success with another, no longer available, library (can't  
remember the name of it off hand, but it seems to have simply  
disappeared off the face of the planet).

Anyway, face stuff in Ansel is still obviously somewhat broken. I  
haven't had time to spend to figure out why facedetect won't  
compile/load on my system so I can't debug it right now.

This works for me. It's how I've been using face support for a while  
now, since I can't get the PECL extension to work right.

Haven't tested IE9 with Ansel. Will have to test next time I load up  
the Windows VM for testing.

If you click the "Edit Faces" link in the "People in this Photo"  
widget, you will get fields to edit/delete each face you've added.

At one point, this defaulted to 5. The entire idea behind how  
libpuzzle works is just not really favorable for such small images  
that all contain faces. I've never gotten this to work to any degree  
of accuracy...and it uses TONS of database storage to store the index  
chunks. I've never liked this feature, but the code was contributed  
and lots of people expressed interest, so...

Well, that's the best value for me :P
